ELEVATED HAY-CARRIER.

SPECIFICATION forming part of Letters Patent No. 714,306, dated November 25, 1902.

' Application filed .Tune 20, 1902. Serial No. 112,481. (No model To a/ZZ whom t may con/cern,.-

Be it known that I, SAMUEL JACOBS, a citizen of the United States of America, residing at Lawrence, in the county of Douglas and State of Kansas, have invented certain new and useful Improvements in Elevated Hay- Carriers; and I do hereby declare that the following is a full, clear, and exact description of the invention, such as will enable others to make and use the same, reference y beinghad to the accompanying drawings, `forming a part of this specification.

Azo

The objects of my invention are, first, in an elevated hay-carrier, to control automatically the locking in position and the unlocking of a fall-rope carrier; second, to retain the movement of an elevated sheave-frame upon the track-rails during the rotation of the frame; third, to enable the sheave-frame to be readily disconnected from the carriage; fourth, the` reversal in position of the locking-lever for long-distance delivery.

The invention consists in the novel construction and combination of parts, such as `will `be iirst fully described, and specifically pointed out in the claims.

In the drawings, Figure l is a view in perspective of the novel hay-carrier, showing the elevated track-rails and the fall-rope carrier for the hay-forkvin a locked position. Fig. 2 is a side view of the invention with one ofthe sides of the sheave-frame broken away tovshow the operative parts. Fig. 3 is a vertical sectionalview of the invention, taken on the line .fr a; of Fig. 2. Fig. 4 is a plan View of the sheave-frame, showing the parts of the top of the frame broken away to show the slide on the inner surface of the top of the sheaVe-frame for engaging with the hollow king-bolt. Fig. 5 is a detail view of the locking-lever for securing the pulleyblock in the sheave-frame.

Similar letters of reference indicate corresponding parts in all the iigures of the drawings.

Referring to the drawings, A A represent parallel track-rails for supporting the sheaveframe, which are flat and of the proper width for the traction-wheels and arranged horizontally in position. These track-rails are arranged a short distance apart and extended the requisite distance in length for the conveyance of hay or other material. Upon the inner edge of one of the track-rails is secured a longitudinal `upright `keeper-plate ct, in which is -a notch a of the proper length. The forward and rear ends of the plate a are inclined in opposite directions from the upper edge ofthe plate to the surface of the track-rails. These keeper plates a are arranged on the track-rail in series and at the requisite distances apart.

B represents the carriage supporting the sheave-frame and which consists of a longitudinal body or block ZJ, arranged within the space between the track-rails A A and extending in height a short distance above a line horizontal with the `track-rails. Upon each side of the block b and near the forward and rear ends are wheels b b b b', which are mounted on journals b2, connected with the sides of the block, and move over the upper surface of the track-rails Without contacting with the plate a. From the sides of the block or body b and at the lower edge of said block extend the guide-flanges b3 b3, which extend upon the lower surfaces of the track-rails and nearly to the line of the outer edges of said rails. Upon the longitudinal edges of the flanges b3 b3, at a point equidistant from the ends of the said iianges, are outwardly-curved extensions b5 b5, drawn upon the arc of a circle and which afford a broad bearing for the sheave-frame, especially in rotation. In the block b, equidistant from the ends of said block, is a transverse slot b4, which extends downwardly nearly to the line of the surface of the track-rails.

C represents the rotatable sheave-frame, consisting of the top plate c, which is of the same length as the block b and which extends in width nearly to the line of the outer edges of the track-rails A A. With the outer edges of the top c are connected rigidly the sidesc2 c2 of the sheave-fralne, which extend downwardly the proper distance to support the operative devices. A portion 'cf of the outer edges of the top plate c of the sheaveframe extends outwardly ashort distance beneath the curved extensionsbfbSof the lianges h3 b3, the outer edges of which describe an arc of a circle of the same degree as the extensions b5 b5. For the purpose of removably connecting the carriage B and the sheave- IOO the inner sides of the frame together in the top c of the sheaveframe at a point equidistant from the ends of said top is a rectan gularshaped opening c3.

In the under side of the block b directly above the opening c3 is a screw-opening b, in which is inserted the screw-threaded end d of a hollow king-bolt D. The lower end of the king-bolt extends through the opening c3, and a short distance below the inner surface of the top c of the sheave-frame C and upon said lower end of the bolt is a square head d'. Through the bolt D extends a longitudinal opening d2.

Within one end of the sheave-frame is inserted a Iiat lockingplate E, which bears against the inner surface of the top c of the sheave-frame, the inner end being cut away at e in the arc of a circle to extend part way around the king-bolt I) and between the upper surface of the head d2 of the bolt and the top c of the sheave-frame, the space being sufficient to admit the thickness of the plate E. The outer end of the plate is secured by a nail-screw passing through the perforations e and into the under surface of the top c.

In the transverse slot b4 in the block b is a latch-barf, which moves freely therein, the ends of which extend beyond the outer surface of the side of block Z) to a point in line with the outer surface of one of the keeper-plates a on the track-rail A. With the latch-barf is connected the upper end of an adjustable rod F, the lower end of which rod is screwthreaded and extends downwardly the proper distance to connect with the reversible locking-lever G. Said lever consists of the side plates g g, which are connected pivotally at g' with the respective inner surfaces of the sides c2 c2 of the sheave-frame near the rear end of said frame and at a point about one-third the distance upwardly toward the top c of the sheave-frame from the lower edges thereof. The forward ends of the lever extend nearly to the forward edges of the sides c2 c2 of the frame C andare connected together by a transverse portion or plate g3. In order to aEord a normal horizontal support for the forward ends of the lever G, the inner surface of the sides c2 c2 of the sheave-frame are inclined inwardly toward each other from the lower edges of the sides c2 c2 and extended upwardly, so as to form the shoulder c4 c4 equal in width to the thickness of the plates upon which the plates g g rest. With the lower end of the rod F is connected a U-shaped strap g4, the ends of which are pivotally connected with plates g g of thel locking-lever G. In the strap g4 is a perforation g5, through which the rod F extends, and upon the said rod is a nut gf", which bears upon the outer surface of the strap g4,and a nut g7,which bears upon the under surface of said strap. In the lower edge of each plate g and a short distance from the pivotal point of the strap g4 in the direction of the forward transverse plate g3 is a semicircular notch g8. Upon the upper edge of the plates gg is a V-shaped depression 99, the angle of one side of the depression being more obtuse inthe direction of the forward end of the said plate g. In the sides c2 c2 of the sheave-frame opposite the plates g g of the locking-lever and the notches gs gS are longitudinal openings c5 c5, which extend a short distance forward of the position of the notch g8 and a distance greater in proportion rearwardly. The lower edge of the opening c5 extends a slight distance rearwardly ofthe rear end of the notch g8 to form a shoulder c6, and from said shoulder the por tion of the sides c2 are cut away in an outwardly and downwardly curved line, as at c7. From the rear upper edge of the slot c5 the side c2 of the frame is cut away in a rearwardly outwardly curved line, as at cs, between which curved line and the curved line c7 is an open space for the entrance of the pin supporting the pulley-block.

I I represent the sheaves in frame C, which are journaled at t' near the respective forward and rear ends of said frame a short distance beneath the under surface of the top c.

K is the fall-pulley block, in which is the pulley k. Upon the upper end of block K is a transverse pin la, the ends of which rest, when the block is connected with the sheaveframe, upon the shoulders c6.

M represents the cable, one end m of which is connected with the upper end of the block K, the other end of which cable extends upwardly over the sheave I at the rear end of the sheave-frame, thence downwardly under the pulley k in the pulley-block, thence upwardly over the sheave I at the forward end of the sheave-frame, thence connected with any suitable means of moving the sheaveframe. With the lower end of the block K is connected the upper end of a rope N, the lower end being connected with a plate o on the spring-plate o of the hay-fork O of the usual and well-known construction, the teeth o2 aiding to grasp the hay in the well-known manner.

In operation and for the purpose of moving quantities of material, such as hay, from one place to another and dumping the hay at various places beneath the track-rails A A the pulley-block K is removed from the sheaveframe C by raising the latch-bar f, the position of the keeper-block ct being preferably located on the track-rail above the position of the hay to be raised, the latch-bar f being within the notch a, and the locking bar or lever G is raised in position, so that the block K may be removed from the openings or slots c5 c5 of the frame C by a swinging motion imparted to the fork-frame O, and under a slack in the cable M the hay-fork is permitted to descend as far as is necessary to grasp a quantity of the hay or other material. Power being applied to draw upon the cable M, the quantity of material is raised with comparatively little power, and as the pin k strikes the curved lines c7 o8 of the entrance to the opening c5 the purchase of the cable M from IIO i of the lever from the pin k.

the forward sheave I will draw the upper end of the pulley-block toward the forward end u of said opening and permit the pin to rest the plate, and during the time'the latch-bar is within the notch a' the lever Ga sufficient distance to remove the notched portion g8 The drawing power upon the cable M is then slackened, and by means of a short rope on the hay for frame O, theframe is caused to swing back and forward, and bya sudden movement the l block K is disconnected from the sheaveframe and thepulley-block and the hay-fork, with its load, deposited in its proper place. Thepulley-block is then raised in position and the pin k seated within theopening o5. The sheave-frame is then rotated upon the king-bolt D and the. direction of movement changed of the frame, as well as the carriage B. The power then applied to draw the sheave-frame in lthe opposite direction causes the pin 7c to thrust upon locking-lever G and raises the latch-bar f out of the notch a in y is repeated.

the plate a, and the frame and carriage B move toward the other end of the track-rails, where the operation of loading the hay-fork When it is desired to hold the pulley-block Within lthe opening c5, so that a sudden throw of the hay-fork discharged of its load will be released from the sheaveframe, the rod F is rst disconnected from the U-shaped strap g4 by the removal of the nut gl. The plate E is then removed from the frame C andthe nut d' of the king-bolt D drawn through the opening c3 in the top c of the frame C, the rod F being drawn from the opening d2 in the king-bolt, and the carriageblock B is separate from the sheave-frame C. The locking-lever G is then removed from the sheave-frame and reversed in position, and at the same time the strap gL1 is also reversed x `inpositionand the locking-lever pivotally i connected with the frame C as before.

The carriage B` and the frame C are then connected and the rod F extended through the king-bolt and connected with strap g4, this i action causing the notch g9`to 'engage with the pin k', the inclined surfaces of the notch affording an easy removal of the pulley-block.

The invention is applicable to the transportationof all kinds of material, or for store service is especially valuable, the movement of the carriage B being actuated by the means employed in i the present well-knowncarrier systems, the cable M in this instance being employed to raise and lower the parallel holders. The latch-barf is adjusted in position by the nuts Q6 Q7, which enables a latch-plate to be less in length or in one continuous length, with notches at short or long dis` tances apart.

Such modications of the invention may be employed as are within the scope of the invention.
